I have wired a push-to-make microswitch to an interrupt pin on my Arduino Mega using an external 1k pull down resistor as shown in the image "pull down connection" here: Inputs The switch seems to reliably trigger the interrupt on close (actually multiple times due to bounce). However, very occasio…
